This question is impossible given the current situation; for the average to equal 20, given 28 and 20 as two of the three, the third must be 12.If it were not stated that 20 was the least of the numbers, then the answer would indeed be 18, but, however, this not being the case, no answer is possible inside of the normal rational number system.

In total, we are changing the sum of the 9 numbers by 1 + 2 + ... + 9 = 9 x 10 / 2 = 45, so each of the numbers is increased by, on average, 45/9=5. If the old average was 40, the new one is 40 + <the average amount each number was increased by> = 40 + 5 = 45.

Average of three = 20 so total of three = 60; 60 - (28 + 15) = 60 - 43 = 17

The average is the sum divided by the number of original numbers. The sum of 132, 140, and 145 is 417. There were three original numbers, so the average is one-third of 417 or 139

The third number is 112, the numbers are 86, 86, 112, 172

Sum = Sum + first number Sum = Sum + second number Sum = Sum + third number Average = 1/3 x Sum

Any three numbers where the sum of the two smaller numbers is greater than the third number. List the numbers in order from least to greatest, repeating any number if necessary. Add the first two numbers together and if this sum is greater than the third number then a triangle with those sides can be made. ie if the sum of the two smaller numbers is greater than the third number then a triangle can be made.

Average of the three is v so their sum is 3v. One is z, another y so the third is 3v - z - y

The third number could be: 3, 6, 15 or 30

Third (or 3rd) is the ordinal form of three.

They are located on the bottom of your checks. First set of numbers in the bottom left are your "routing number" to your bank. The second set of numbers is the checking account number. The third set of numbers is the actual check number (should match the number in the top right corner.)

It average of 2 numbers is 9 then take 9 away from 12, so average of 3 numbers is now 9, with 3 'left over.' The 3 which is 'left over' divides among the three numbers by adding 1 to each of them, raising the new average to 10.

It depends on the set of numbers that you have and where, within that set, you start.

In large numbers, a comma precedes every third number (counting from right to left). So, 3000000 should be written as 3,000,000.

If the numbers are consecutive then the middle number must be one-third of 51. The numbers are thus 16, 17 and 18.
